i'm currently running the greddy turbo kit for the 1.6 as well.
i wanted to upgrade to a slightly bigger turob, what suggestions do you guys have for a bit bigger, and ball bearing if possible.
has to be the same flanges and everything because
i already bought a DP made by turbo tony already and dont want to reinvest in another.

well i have bad news for ya the greddy turbo has weird flanges that you probably wont find on other turbos so you're screwed unless some one else knows of another turbo. the greddy can get you to 270 or so whp how much more do you want.

well i would agree that the greddy can put you into the range of tranny danger but maybe it could be done more efficiently with a better compressor wheel, maybe not even lose any spool? i think i'd like to get markp's input as i'm not really even sure what's involved with mixing and matching turbo components

well, i am running at 10PSI, my goal is to make 250WHP
i currently have like almost all bolt ons, looking to do cams sometime soon
looking at maybe some HKS 264 exhaust 256 intake, camshafts blah blah blah
thicker head gasket, resurface head, new valve springs, maybe even new valves, and a valve job.

i did notice that the td04h-15g has a really weird flange, took me forever to even located someone that sells it.

from my knowledge, running the turbo effeciently only goes up to 10 or 12lbs?
